The House Select Committee on Benghazi will not be calling former secretary of state Hillary Clinton to testify before their panel after its chairman, Rep. Trey Gowdy, R-S.C., told Secretary of State John Kerry that the lack of disclosure of documents by the State Department has been hindering progress.

“Secretary Clinton is insistent she will appear once and only once before the Select Committee,” Gowdy said in a statement Thursday. “The Committee must be equally insistent that her appearance is thorough and fully productive. This requires the record to be complete so the Members can effectively base their questions on documents and the Secretary can base her answers on those same documents.”

Gowdy told Kerry in a letter that he wanted Clinton to come to the committee to discuss the private emails that came to light in March.

In an effort to ensure her public record was complete, we invited the former Secretary to explore the unusual email arrangement she had with herself while serving as Secretary. Secretary Clinton rejected our request that she provide her server, which houses public records, to a neutral, third party arbiter. She also rejected our invitation to testify in a transcribed interview.

Secretary Clinton has insisted she will appear before our Committee a single time. Consequently our Committee is equally insistent any appearance be as thorough and constructive as possible.

In the letter, Gowdy also told Kerry that “it is impossible for the Committee and the former Secretary to constructively discuss policies, decisions, and activities, related to Benghazi without your Department cooperating efficiently with the legitimate requests for relevant and salient information,” National Journal reported.

In fact, not a single document has been produced by the State Department pursuant to these requests despite the Committee’s successive efforts, at the State Department’s insistence, to narrow its request.

“Simply put, the Committee must have the records of communication requested more than six months ago before the Secretary’s appearance can be scheduled,” he wrote. “There is still the possibility of scheduling the former Secretary’s appearance soon, but that is contingent upon Department of State compliance.”
